There was a 500-pound bear sound asleep on the floor.
The bear had been spotted wandering in the neighborhood in Hopatcong earlier Wednesday. It's not clear how it got into the home.
The bear ambled out of the house before state Fish and Game officials arrived.
A local television station in New York reports the officials fired a tranquilizer dart at the animal, which walked a few blocks to the Missouri Trail before it was knocked out.
Officials plan to relocate the bear.
No one was injured.
